Dude, it's mostly ethanol. Worse mileage. Much worse. Ethanol per unit volume produces less energy when combusted than does gasoline. BUT, the intercooling properties of E85 and the inherent knock resistance means that you can tune for MORE power with it than with gasoline. You just have to flow lots more of it per injection cycle.
